Scientific Insights:

We have all played with balloons before. When we inflate them fully, put our mouths downward, and let go, we hear the sound of air escaping from the balloon, and at the same time, we see the balloon rise upward. But do you know why the balloon rises? Let’s get creative and make an interesting balloon plane together.

Experimental Objectives:

1. Understand the balloon helicopter and its structure
2. Cultivate children's ability to observe, experiment, and perform hands-on activities

Experimental Cognition:

Flight Principle: Jet aircraft utilize aerodynamic principles. They harness the contraction force of balloons to induce air flow, which drives the propeller to rotate and generate power, enabling the entire toy to rise smoothly. Additionally, a portion of the airflow is directed to the sound device, producing pleasant sounds that are very attractive.
Aerodynamics: It is a branch of fluid mechanics that primarily studies the forces generated when objects move in air or other gases.

Scientific Production:

1. Experimental preparation: Identify the experimental equipment including balloons, air nozzles, interfaces, and propellers
2. Attach the propeller and the interface together; and place the balloon over the air nozzle.
3. Inflate the balloon, then pinch the opening of the balloon to prevent air from escaping;
4. Hold the balloon with your hand and connect the air nozzle to the interface equipped with the propeller.
5. Hold the balloon helicopter, position it parallel to the line of sight, then release it to make it fly.
Note: When squeezing the balloon and the interface together, make sure the air inside the balloon does not leak out, as this may affect the flight performance of the balloon helicopter.

Scientific Principles:

Aerodynamics principles.
The balloon and propeller interface is connected via a nozzle. The interface and the three propeller blades are at a certain tilt angle from the horizontal. The propeller blades are hollow, serving as air passages, and have exhaust holes. Using the contraction force of the balloon, air flows within the propeller blades to the exhaust holes for expulsion, generating power. This causes the three propeller blades to rotate, allowing the entire aircraft to fly while rotating, and some air flows into the whistle, producing a pleasant sound as the jet rises during rotation.

Scientific Expansion:

Aerodynamics is widely used in aerospace, such as jet aircraft and artificial satellites. In addition to the development of aerodynamics driven by advancements in aerospace technology, since the 1960s, it has also been influenced by developments in transportation, construction, meteorology, environmental protection, and energy utilization.

Please check that the circuit is unobstructed and all components are intact before assembly, as well as ensure all contact points are properly aligned. During assembly, be careful not to let glue get on your clothes or skin. Keep the components out of reach for younger siblings to prevent them from accidentally swallowing them! Do not play with them on your head, as the model may fall and hurt you!
